PUMP.

SPECIFICATION forming part of Letters Patent No. 242,140, dated May 31, 1881. Application filed lFebruary E2, 1881. (No model.)

To all whom t may concern:

Be it known that I, WILLIAM S. LANEY, a citizen of the United States, residing at Lithopolis, in the county of Fairfield and State of Ohio, have invented certain new and useful Improvements in Pumps; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

This invention relates to double lifting pumps; and it consists in the construction and arrangement of the several parts hereinafter described, and pointed out in the claims.

In the drawings, Figure lis a side elevation, and Fig. 2 is a vertical section, of a pump constructed according to my invention.

a a' are two outer or stand pipes, and a2 is an intermediate air-pipe placed between the stand-pipes, as shown. The lower ends of these ,three pipes are connected together by a horizontal confluent tube or pipe, a3.

a4 is a supporting-tube lmade of such length that its lower end will reach to and stand on the bottom of the Well, or on a base specially provided forit. It is connected so that its bore is in direct line with the bore of one of the stand-pipes, so that the piston placed in it can be operated by a rod carried up through standpipe above it.

The upper end of the intermediate air-pipe, a2, is closed tight, and serves as a fulcrum to which the handle bis pivoted. The upper ends of the stand-pipes a a are closed by caps a5, having vertical holes,through which the pistonrods c c' pass downward into the said pipes. The handle b is arranged in line with the three pipes, and is so constructed that both pistonrods are attached to it by means of the connecting-link o2 cz. The rods c o are packed airtight in the caps a5, so that the pipe a, above its connection with the confluent pipe, and the pipe a', above the discharge a, become airchambers, into which the air will be more or less compressed inthe operation of the pump. The center pipe, a2, also is an air-chamber, into which the water will How and compress the air upward. The piston-rod o extends below the continent pipe a3 into the extension a4, and is provided with avalve-piston, o3. Thelower end of the extension a4 rests on the bottom of the well, and the piston c3 is placed so as to be below or very near the surface of the water. If it be arranged to play above the water-level, a check-valve should be placed in the pipe below it, as in the ordinary sucker-pump. A check-valve, d, is placed near the upper end of the extension a4 and below the end of the conliuent pipe a3.

The valve-piston o4 on the piston-rod c plays in the lower end of the stand-pipe a and between the spout a6 and the confluent pipe. lt is arranged above the level of the lower ends ot' the three pipes a a a2.

A check-valve, if desired, may be arranged at all; but its presence is not indispensable, for the pump will operate Well Without it.

The three pipes may be held in place by any suitable braces-as, for example, the crossbar e.

The several pipes described hereinbefore may be of any desired length, the relative arrangement of parts being preserved.

The device is specially adapted for deep-well service. A double-lift pump is furnished from which an unintermittent flow ot' water can be had.

The operation of the device is readily understood. The piston o3 lifts the water into the confluent tube. Considerable quantity of the Water will be forced upward into the pipes a a2. The water, after it has passed through the conuent tube, is taken by the piston o4 and lifted to the discharge a6. It' the pump be operated very rapidly, much of the water will be lifted above the discharge a6 into the air-chamber in the upper end of the pipe a.

By the construction hereinbefore described it will be seen that I have three air-chambers into which the air will be compressed as the water is drawn upward. This compressed air operates to maintain an unintermittent iiow of water.

The central stem, a2, contains the main airchamber, from which the chief benefits of the compressed air are received. The stem serves as a fulcrum for the handle, which is so arranged as to oscillate on its pivotal connection and move the pistons c3 c4 in opposite dI- reetions at the same instant. When the handle is moved so as to raise piston e* the latter acts as a sucker and draws a `greater quantity of water through the piston c than would other Wise be brought upward by the said piston e" it' used alone.

The central pipe, a?, eould be dispensed with and the handle be pivoted on a suitable framing connected with the pipes (t u. Excellent results would be thus obtained; but I prel'er in all eases to have the eentral air-pipe an ranged as shown and described.

Having thus described my invention, what I claim, and desire to seeure by Letters lateut, is-

l. 1nadouble-acting'suekerorlil'tpnnip, the

Combination of two stand-pipes having` air Chambers in their upper ends, a contluent pipe uniting the lower ends of the stand-pipes, a supporting-pipe orextension eonneeted to the lower end ot' one of the stand-pipes. a piston placed in thestand-pipe, t'rom whit-h the water is discharged, and arranged above the end ot' the eontlnent pipe, a piston placed in the sup porting-pipe or extension below the end ot' the eontluent pipe, together with the necessaryY cheek-valves, piston-rods, and operating;` meehanisins, substantially as set forth.

2. Ina double-acting` suekeror lift pump, the combination, with the stand-pipes a tt', having' their lower ends united by a confluent pipe, afi, ot' the air-tubet, having its upper end elosed and its lower end open and connected to and openingv into the eontluent tube a at a point between the stand-pipes, and having suitable lneans on its upper end for holding the lever b tor operating the piston-rods and pistons in the .stand-pipes, substantially as herein set t'orth.

In testimony whereof I attix my signature in I presenee oi' two witnesses on this 24th day oi` January, lbbl.
